Lipids are soluble in organic solvents.
All lipids contain fatty acids.
There are many different types of lipids.
7 Which of the following is not a function of lipids in the human body?

the cis double bonds give them an irregular shape.
the trans double bonds give them an irregular shape.
they have more hydrogen atoms.
they have fewer hydrogen atoms.
palmitoleic acid
stearic acid
linoleic acid
linolenic acid
waxes
triacylglycerols
phospholipids
steroids
chitin
Explanation / Answer
1) True
2)Like chloroform, dichloromethane, etc
3) Chitin (is a long-chain polymer)
4) False
5) Unsaturated fatty acids (if more then called polyunsaturated fatty acid)
6) All lipids contain fatty acids, this statement is false
7) pH regulation.
8) carbon-carbon double bond
9) Because of the trans double bond the packing will be good and proper, as a result the unsaturated fatty acids will be having less melting point than the saturated ones.
10) Stearic acid (Mp: 69.5
